The antonyms for "putting fire" can be as diverse as extinguishing, dowsing, cooling, calming, or pacifying. These words are used interchangeably depending on the context of the sentence. For instance, if a fire is out of control, one can say that firefighters are extinguishing the flames, or if someone is angry, another person can try to calm them down. Likewise, in some situations, putting fire in something, like fuel or wood, can be necessary or helpful, and there aren't necessarily antonyms for that phrase. The importance of using antonyms in language is to create balance, and to be able to express the full spectrum of emotions and actions that exist.
